Abstract

Raman spectroscsopy is used for studying molecular transport junctions (MTJs), but it cannot distinguish molecules participating in electrical transport from nearby inactive molecules. Here, on-wire lithography-generated nanostructures are used to study MTJs through inelastic electron tunneling spectroscopy complemented by Raman spectroscopy to fingerprint the molecules participating in electrical conduction, while observation of host-guest interactions confirms their functionality.
